Abstract :
A per-survivor processing (PSP) sequence detection receiver is proposed for DS/CDMA systems with pilot and traffic channels. The proposed receiver jointly estimates channel parameters and data symbols from pilot and traffic channels, and is derived by modifying the receiver of Choi (see IEEE Proc. Commun., vol.146, no.5, p.1-7, 1999). As a result, the new receiver can outperform the receiver of Choi in exchange for additional computation. Computer simulation results demonstrate the advantage of the proposed receiver over existing ones.
